Thailand is well known as a source of workers who engage in transnational migration (see Hewison Chapter 6, this volume). Less well recognized, at least outside Thailand, is the fact that the country also receives very large numbers of transnational migrants who move into the country in search of work. Most of these migrants are from the poorer neighbouring countries of Burma (Myanmar), the Lao People’s Democratic Republic (Lao PDR or Laos) and Cambodia. Those countries that Thailand borders which have experienced later and less capitalist development and where there have been decades of political instability and war, has meant that, in recent years, it has resulted in an increasing influx of migrants. Some of these have been refugees, but in recent years, the migrants have been in search of work and ways to improve their lives.
